The Rules Engine is part of the Polaris platform (formerly DHOS). This service is a Node.js microservice to expose an API for a rules engine.
The rules engine is "JSON Rules Engine" (https://github.com/CacheControl/json-rules-engine)
This service is intended to be wrapped by the Polaris PDF API. This service is expected to be running locally. For this reason, the API exposed by the Rules Engine is not protected by endpoint security.
yarn install
yarn build
yarn test
yarn startdocker build -t dhos-rules-engine/v18.1 . # once
docker run -p 3000:3000 -t dhos-rules-engine/v18.1The service exposes each rule type as an importable script. It requires an import of moment.js.
